Title: Ammunition unit
Inventor: MATTSSON KJELL
IPC: F42B10/52
Filed: 1982-09-08
Abstract: There is provided an ammunition unit, preferably for training purposes, intended to be fired from a gun barrel at supersonic speed. The ammunition unit comprises an intermediate body part (1) to which is connected a substantially cylindrical spike (2) as well as a finned tail section (3). The length (L1) and design of the spike and the design and connection of the tail section to the intermediate part are such that the ammunition unit, up to a predetermined firing distance, has substantially the same ballistic properties as the equivalent normal live ammunition but which has a significantly reduced maximal firing range as compared with such normal live ammunition. This is because a dead air stream zone is obtained around the spike at supersonic speeds, but at sub-sonic speeds the air stream follows the spike surface and results in a substantial braking force. The length L1 of the spike is 1.6-2.0 the diameter D of the body a truncated conical part 1a of the body has a length of 1-3% of the total length of the unit and a conical angle between 10 DEG and 20 DEG .

Title: Laser with recombination catalyst
Inventor: RUDKO ROBERT I
IPC: H01S3/036
Filed: 1983-05-20
Abstract: In a laser 10 using an electrical discharge produced between a pair of electrodes 14, 16 a catalyst 30 is used for the recombination of gain medium 13 components dissociated by the discharge. The catalyst material 30 is confined by a catalyst container 40 made of conductive material. The container 40 includes a cover 28 having apertures smaller than the smallest catalyst particle and bigger than the molecule size of the gain medium 13. The conductive surface of the container 40 forms a cage which protects the catalyst 30, usually a powder, from the dispersing effects of the large electric fields present in the laser, and the aperture size allows the gain medium 13 to come into contact with the catalyst 30 while preventing the catalyst powder 30 from dispersing throughout the laser. The container 40 is placed in contact with one electrode 16 in order to transfer heat from the electrode 16 to the catalyst 30. The electric discharge causes some gain medium to pass over the catalyst 30 and the increased temperature of the catalyst 30 improves the recombination rate. <IMAGE>

Title: Fabric cutting device and apparatus
Inventor: CLARKE FRED
IPC: B26D7/24
Filed: 1983-12-22
Abstract: A cutting device for cutting moving fabric into widths comprises a cantilever cutting bar means 50, which has at least one reciprocable cutting blade (70 Figure 3). The fabric is guided into a notch 68 in a guide bar, and the blade reciprocates across the notch. Preferably the blade is reciprocated in a pulsed fashion by means of a solenoid 44 and return spring 54, and the solenoid is contained in a casing 34 and the casing and cantilever guide bar and cutting blade can be pivoted as a unit on a mounting bracket 24 which positions the cutting device in relation to the moving fabric. The pivoting of the casing and cantilever guide bar is resisted by holding means such as magnets 100, but the holding means will be overcome when the load and the cantilever guide bar becomes excessive (as a result of malfunctioning or inefficiency of cutting), and the pivoting of the casing operates a microswitch which in turn causes the feed of the fabric to stop. <IMAGE>

Title: Improvements in or relating to apparatus for aircraft for use in blind landings or blind take-offs
IPC: G01S1/02
Filed: 1956-02-28
Abstract: 834,409. Aircraft instruments. KONINKLIJKE LUCHTVAART MAATSCHAPPIJ N. V., DERKSEN, J. W., and KIPS, E. J. E. Feb. 28, 1956 [March 7, 1955], No. 6196/56. Class 4. An aircraft instrument for use during blind take-off and landing conditions comprises a screen V having a vertical axis Y-Y along which an aircraft silhouette Q is moved under the control of an altimeter against a scale h graduated to give an indication of altitude, the distance y representing the actual height of the aircaft above a runway. The ideal height is indicated by a line I which is moved vertically over the screen in response to signals from a ground-based glide-path transmitter. An arrow N at one end of line I indicates on a scale x the momentary distance of the aircraft from the point of touch-down on the runway. A line W is adjustable in height to give an indication of cloud base and a further line Z is coupled to the movement of the vertical pointer of a zero-reader to give an indication of the lateral position of the aircraft with respect to the longitudinal axis of a landing runway. A pointer m moves along scale x at a rate to indicate the desirable speed during landing. The silhouette Q may be inclined about axis q to indicate angle of bank and a further silhouette (not shown) may be moved along a scale C2 over a model runway H to give an indication of the position of the aircraft along the runway. The runway H may be swung about a pivot F to indicate the lateral position of the aircraft with respect to the actual runway. The screen Y is transparent to render runway H visible. In a further embodiment (not shown), the screen displays a view of a runway as viewed from a side thereof in which the cloud base line W and the desirable rate of approach m are shown, the ideal and actual flight paths being shown in traces on the screen, which is formed as a cathode ray tube. The instrument may display light signals or give acoustic warning when the aircraft passes selected limits on the runway or such signals may be used to warn the crew that certain operations, e.g. of undercarriage, flaps, propeller pitch should be carried out. Specification 790,934 is referred to.

Title: Electric water heaters
Inventor: LEWIS ROBERT
IPC: F24H9/20
Filed: 1984-05-18
Abstract: In order to enable water to be heated rapidly or in relatively large quantities. particularly for use in showers, an electric water heater 15 provided which is capable of overloading the supply circuit for a limited period. The heater also includes a monitor which may operate as if it contained a register which keeps a running total of energy variation that is the extent to which the energy used by the heating means exceeds the energy that would be dissipated if it ran at the maximum supply current without overloading the supply circuit if that running total exceeds a set value the monitor takes steps to prevent this continuing. It may switch off the heating means or reduce its power output so that it no longer overloads the supply circuit. The monitor may comprises microprocessor. Water to be heated may pass from an inlet duct 20 to two parallel ducts 22, 23 containing heaters 26, 28. The ducts lead to an outlet duct 25 containing a thermostat probe 29 which causes appropriate variation in the first heater (26). When an on/off valve 27 is closed water is heated by the first heater using a normal current. Depression of a button opens the on/off valve 27 and switches on the second heater 28 so that the supply circuit is overloaded. The monitor operates to close the on/off valve and cut off the power supply to the second heater when the excess energy running total reaches the set value. <IMAGE>

Title: OTDR for sensing distortions in optical fibres
Inventor: THORNTON SHANE
IPC: G01S17/10
Filed: 1984-09-29
Abstract: An optical sensing system comprises a highly birefringent optical fibre 5 having two principal polarisation axes. The optical fibre 5 is arranged to be subjected to deforming forces such as acoustic waves. The optical fibre 5 is divided into a plurality of elements by discontinuities 7 to 15 so that a small proportion of coherent light transmitted along either axis of the optical fibre 5 will be reflected back along the fibre 5 at each. The reflected light pulses interfere with each other within either axis of the optical fibre 5, and after leaving the optical fibre 5, they are passed to a photo- detection means 19a, 19b and decoding means 20a, 20b from which signals indicative of changes in optical length of the elements are produced. There is substantially no interaction between light passing along the two axes, and so by transmitting a first pulse train of one polarization along one axis and a second pulse train of a second polarization along the other axis, the bandwidth of the system is effectively doubled. <IMAGE>
